  • Patent number: 5279092
    Abstract: A rigid patch body for placing over and around a damaged portion (hole) of the external wall of a pressurized vessel, such as a space vehicle or habitat. The rigid patch body allows a person such as an astronaut to make temporary repairs to the pressurized vessel from the exterior of the vessel to enable more permanent repairs to be made from the interior of the vessel. The pressure wall patch of the present invention includes a floor surrounded by four side members. Each side member includes a threaded screw for anchoring the patch body to the external wall of the pressurized vessel and a recess in its lower surface for supporting an inflatable bladder for surrounding the damaged portion (hole) of the external wall to seal the area surrounding the damaged portion to allow the vessel to be repressurized. The floor of the rigid patch body supports a source of gas in communication with a gas supply valve and a gas supply gauge in communication with the gas supply valve and the inflatable bladder.
